Note:
Codes must be entered during a fight, and only last for the duration of that fight.

Camera man (one player game):
Press B, A, Left(2), A, Down(2), A, C, A, B, A, Right, A. This code will give camera control to controller two during a one player game. The camera operates in the same manner as during an instant replay.

Camera man (two player game):
With three controllers available, enter B, A, Left(2), A, Down(2), Right, A, Down, A, Right on controller one. This code will give camera control to controller three during a two player game. The camera operates in the same manner as during an instant replay.

Save file (this option is disabled)
Paste (allows objects to be pasted)
Delete (allows objects to be cut)

While in an editor option, B cycles through actions, C executes the current selection, X allows the current level to be played, and P displays the editor option screen.

All levels/worlds:
From the world or level map, press P to display the remote control bar. Then, hold RS and press Left, C, Down(2), P, Right(2), A, Down. Use this code from the central area with Rez's dome in the center to turn on the TVs and allow any world to be entered immediately. Use this code from within a world to turn on all TVs to allow any level in that world to be entered immediately.

Long ending:
Hold RS and press Left, C, Down, B, A, Down, Up, Right, Left, Down, B, Right, A, Right, Down at the title screen. The long ending of the game will be displayed, which includes sketches and graphics that were used during its development. This is the ending is normally seen only after the Planet X level has been completed.

Planet X level translation:
0:SCIFI1 is Clothesline
1:SCIFI2 is The Web
2:SCIFI3 is Free Fall
3:SCIFI4 is Bombs Away
4:BONUS7 is Saucer Section
5:MAINMAPS (SCIFI) is the Planet X world screen. Press X to return.
6:SL67 is Newton's 4th Law
7:SL68 is The Project
8:SL69 is Head To Head
9:SL71 is the secret Planet X Boss level.
The Planet X Boss level was never intended to be in the game. One of the programmers was done early and decided to add an extra feature. The Planet X Boss level was the result, but was unfinished and left out of the game. The premise behind this scenario is that the Boss, a robot, tries to shoot Gex with a shrink ray. After a while, a green orb will fall from the ceiling. Gex will grow larger each time he eats the orb. If Gex can eat the orb three times without being shrunk, he will be large enough to defeat the robot. After the Boss is defeated, and the game is allowed to continue without pressing the D-pad, Gex will eat various objects that will appear on the screen.
Lost levels and level select:
From the world or level map, press P to display the remote control bar. Then, hold RS and press Left, C, Down, Left, Right(2), Up, Right(2). A level select screen will appear.

Passwords:
The passwords consist of rotating symbols that have the following appearance:

A: A central sphere connected to six smaller orbiting spheres by lines.
B: A central sphere connected to four smaller spheres by lines and a circle.
C: A central sphere surrounded by two rings
D: A central sphere orbited by four unconnected smaller spheres
E: Six spheres connected by lines forming a hexagon.

Anvil is a special character in the sense that he can float in the air by continuously pressing Up. This way, he can avoid a lot of attacks. The best strategy for winning as Anvil is by constantly sliding into the opponent and uppercutting him. This is very effective in the corners.

The best move for Erika is the throw (Back, C). Her sword's reach is so great that she can throw an opponent from afar. With practice, your opponent may be thrown multiple times. Another good move is the sword uppercut. With correct timing, Erika can just wait until an opponent comes near and uppercut the poor soul with her Katana. The groundfire is good when the opponent is in medium range.

Carlos' strength lies in his shotgun. Blast away at an opponent from afar and, when he gets near, disappear. For close quarter combat, his uppercut is pretty powerful and, the throw is effective as well. When an opponent is too near, try the knee smash (Back, B) repeatedly. Do not get into an air duel since Carlos does not have any aerial attacks.

Riggs is convenient in the sense that his disappear is very close to his hellfire. This way, he can blast an opponent from a distance and disappear when the bad guy is too close for comfort. A good combo for Riggs is a flying kick and an uppercut followed by a roll. This is very lethal and does a lot of damage.

Sasha is very quick. Her drawback is that when she does get hit, she is slow getting up. Her best non-special move is her air attack. That is, constantly jump over an opponent and press B when you are near/above them. Opponents have a difficult time countering this move and, it creates a lot of damage. Her crouch knife is also effective because it comes in so low that it is almost impossible to defend against.

Gabriella can fry you with her eyes. Mesmerize is pretty strong, except that it shoots too high and, the range is limited. So, for consistency, use her fireball. It has good distance and the height is just right to fry anyone. Again, she has a good flying kick, uppercut, cannonball combo. Also, her footsweep (Back, B) has a longer range than normal. Keep opponents at bay by constantly footsweeping them from a distance.

Viper is the most complete and balanced fighter. He has all the necessary moves. He is cat quick and has an array of deadly combos. He can "juggle" opponents fairly easily. Flying kick an opponent then, while he is still in mid-air, give him a couple of high kicks, then finish him off with an uppercut. Another effective combo is slide, slide, uppercut and throw.

Passwords:
A Jumpgate code is revealed after each system is completed. These codes may be manually entered to access a particular system. The codes consist of six of the fifteen total symbols available. Refer to the symbols as arranged in three rows (A, B, and C) of six symbols each, except row C which only contains three symbols:
